Market profile indicator for the ProRealTime trading platform, designed to analyze and display the distribution of trading activity over the current day. It calculates the market profile by examining the price levels at which trading activity occurs and highlights areas of high and low activity. This script employs several key features:
- Dynamic Range Calculation: It calculates the highest and lowest price levels within a specified period, adjusting dynamically as new data comes in.
- Volume Analysis: The script assesses the volume of trades at different price levels, identifying areas with significant trading activity. This feature uses an array to track the number of touches (i.e., instances where the price hits a specific level) to determine the most traded price levels (MaxTouch1 and MaxTouch2).
- Standard Deviation and Center Line (CL): It computes the standard deviation of prices to determine the volatility around the mean price level, along with the center line, to outline the Value Area High (VAH) and Value Area Low (VAL).
- Visualization Enhancements: The script uses rectangles and text annotations to visually represent the market profile, including the opening (O) and closing (C) prices, VAH, and VAL. It also highlights the highest and lowest prices reached within the session and marks specific periods of interest, such as the Asian session or periods of imbalance.
- Customizability: Parameters such as the period for calculations, ATR (Average True Range) for volatility assessment, and specific session times are customizable, allowing traders to adapt the indicator to their specific needs.
This indicator is particularly useful for traders who rely on volume profile analysis to make informed decisions, offering insights into where and how much trading activity is occurring at different price levels. It helps identify key support and resistance levels, areas of consolidation, and potential price movement directions based on historical trading activity.

Sembra molto interessante e volevo dei chiarimenti se possibile :Le righe commentate vanno lasciate cosi come sono? Potresti inoltre spigare le funzioni delle varie linee?
Grazie
Thank you @philippe59139 !! We finally have the VAL / VAH to play with.
Could you attach the screenshot in higher resolution ? Merci 🙂
